Lab Scoreboard

Lab Walkthrough Video:


Performance monitoring and tracking tools can provide a wealth of information about a running system. In some cases, they can help identify anomalies which could have been caused by a security incident.

In this lab, we will analyze Execsnoop script's trace logs to unearth suspicious activity. Please start the lab, answer the below questions and submit the flags to verify:

  1. The ransomware contacts the Command-and-Control server to register and fetch the encryption keys. What is the domain name of the Command-and-Control server?
  2. What is the password used for encrypting the files?
  3. Which encryption scheme is used to encrypt the files?
  4. The ransomware periodically tries to resolve the IP address of a kill-switch server. What is its domain name?
  5. The ransomware prepares a status report file and sends it to the Command-and-Control server. Provide the full path of the status file.
  6. Retrieve the flag kept in the status report file.

Technical Support for this Lab:

There is a reason we provide unlimited lab time: you can take as much time as you need to solve a lab. However, we realize that sometimes hints might be necessary to keep you motivated!

We currently provide technical support limited to:

  • Giving hints for a lab exercise
  • In rare circumstances, if you have totally given up (NO!!!) then tell you how to solve it. This will be limited to sharing the solution video or lab report
  • A lab exercise fails to load or has errors in it

If you need technical support, please email  attackdefense@pentesteracademy.com  clearly mention the name and link of the lab exercise and other essential details. The more descriptive you are, the faster we can help you. We will get back to you within 24 hours or less.
